People become too happy in success and forget their duty at hand. We may get too complacent or proud at a small success, reducing our chances to reach higher goals. Again, at bad times, if we are too grieved, we may lose our faith and confidence. In both cases, our regular course of work is hampered. That is why the poet calls triumph and disaster ‘two impostors’.

Therefore, he asks us to treat those deceivers similarly, with a smiling face. In short, we should not be too happy or too sad under any circumstances.
